Tankless Water Heater Denver

Tankless water heaters are becoming more popular every day. The reasons are they are more energy efficient than traditional water heaters because they heat water “on demand” as it is used, rather than heating and reheating water in a standard tank. They also are significantly smaller than a normal water heater tank, so they require less space in your home – they are wall mounted.

People that have installed tankless water heaters are very happy with the results. We install most brands of tankless water heaters including indoor and outdoor units. If you need help deciding which tankless water heater to get or have more questions, call us today to learn more.

Advantage of Tankless Water Heaters

Endless Hot Water

Tankless water heaters heat water on-demand, so hot water will does not run out. This is beneficial for homes with large hot water demands. For example, if you have a large family, or your home has a hot tub or spa system. If you have been thinking about upgrading your standard tank size from 40-50 gallons to 66-80 gallons, you should consider a tankless hot water heater system.

When you are comparing traditional hot water tanks, the factors include gallon capacity, recovery rate and first hour rating. Tankless hot water heaters are evaluated based on flow rate. As long as the home uses hot water at a flow rate below the tankless heater’s maximum flow rate, there is no lacking of hot water. In general, there is unlimited usage in the first hour.

It is important to understand that tankless water heaters do not provide “instant hot water” the hot water takes time to flow from the unit to the faucet.

Less Space Needed

The space required to install a tankless heater is significantly less than standard heaters. This enables you to put the tankless in a smaller area, or free up additional space in your home or garage. Tankless units save space because they are mounted on the wall and do not have a large water storage tank like traditional units. There are tankless heaters that are installed on the exterior of your home, taking up zero indoor space.

Energy Efficiency

The most efficient traditional gas water heaters have 62% efficiency rate. Tankless heaters have an 80% + efficiency rate. With tankless units, the water is not being constantly heated, cooled and reheated within a tank, saving energy. A tankless hot water heater maintains its efficiency over time, whereas a standard tank loses efficiency.

You can experience a 30-60% savings in water heating energy costs, with your normal water usage habits. Average annual heating water energy costs in homes range from $150 to $400 per year.

High Quality and Longer Life

Tankless heaters will perform well for 20 to 30 years, whereas standard water heaters typically last 8 to 12 years. Tankless water heaters are built with top components and materials, and are less susceptible to rust and leaks.

The higher installation investment of a tankless heater can be recovered over time.

Home Resale Value

A tankless unit may increase the value of your home, and the cost of installation or more may be recovered in this increase as well.

Types of Tankless Water Heaters

There are three types of tankless hot water heaters:

Non-condensing: First generation of tankless heater. This technology has been used is well proven, and has been utilized in Europe and Japan for decades. Reliability is the primary advantage of non-condensing units as they are established products with few manufacturing issues.

Condensing: Second generation tankless heater. These have primary and secondary heat exchangers. The secondary heat exchangers reuses the heat from the exhaust to heat the water. This results in an increased efficiency of 92% to 94%.

Condensing hybrid: Third generation of tankless heater. These were developed in the United States. These heaters use a small 1 liter to 2 gallon holding tank. The small holding tank keeps a reservoir of hot water, eliminating lower efficiency for short draws, meaning these water heaters achieve a true EF of .92-.96.

Tankless Water Heater Installation Costs

The cost to install a tankless heater can vary greatly. We would need to put together an estimate in order to determine total cost. Total cost ranges from $2,000 to $4,500 installed.

In order to install the unit properly, your home must have the following:

Gas or propane and normally we have to run a dedicated gas line to the unit because tankless heaters require up to 200,000 BTUs at full fire.

Category-3 stainless steel or PVC venting installed. This may require us to relocate the heater to an exterior wall or outdoors.

Install additional piping if we need to relocate the heater.

Run dedicated power to the tankless heater. If there is a power outage, the tankless unit will not provide hot water. However, we can install a backup battery system.

If you are replacing an existing tankless water heater or your home is new construction and set up for a tankless unit, the installation costs drop dramatically.

Tankless Water Heater Repair Denver

Tankless water heaters heat water “on demand” on an as needed basis, so they do not experience the always on wear and tear as standard hot water heaters. Because of this, tankless heaters can have lifetimes twice as long as standard units. If you water is very “hard” or has a high mineral content, we recommend flushing your tankless heater regularly.
